Traffic blocked on UDP port 15003

Hi all,

I am trying to use an application that listens for incoming traffic on UDP port 15003, 
and it keeps complaining that the port is blocked. 

I thought it might be the router, so I tried to run the program on a friend's computer 
(I live in a university dorm), and everything worked perfectly. Therefore, I concluded 
it must be my machine that gives me trouble.

From there, I shut down my ZA firewall (I never used the WinXP one, it's been off 
forever). There is no other application that I can think of that could be blocking 
ports (of course, I don't have more than one firewall installed). 

I checked the PID of the program I want to run, then looked up the connections on 
netstat, and I can see it appear in the list:

UDP    0.0.0.0:15003          *:*                                    592
[dtella.exe]

So it must have been able to open the port and bind to it, but apparently it receives 
no traffic on it... What could be the problem? Honestly, at this point, I am lost 
and I don't know what else I could try. 

Thanks in advance for any suggestions you might have.
